Abstract: A plastic food container includes a lid and a base. The lid includes a continuous first body portion and a continuous first rim encompassing and projecting laterally outwardly from the first body portion. The first body portion includes at least one lid partition dividing the first body portion into at least two lid compartments. The lid partition includes, in cross-section, a generally inverted trough-shaped female partition member. The first rim includes, in cross-section, a generally inverted trough-shaped female peripheral member. The base includes a continuous second body portion and a continuous second rim encompassing and projecting laterally outwardly from the second body portion. Like the first body portion of the lid, the second body portion includes at least one base partition dividing the second body portion into at least two base compartments. The base partition includes, in cross-section, a generally inverted trough-shaped male partition member. The second rim includes, in cross-section, a generally inverted trough-shaped male peripheral member.

Abstract: A natural draft, gravity feed pellet stove.  The body of the stove is  formed by a vertical section of large diameter pipe, with an air intake pipe extending from the back of the stove to below a combustion grate.   Pellet fuel is discharged onto the grate through a slot at the bottom of a hopper, and the grate is sloped so that the pellets roll away from the slot and over the grate as they are  combusted.    The  combustion  gasses  flow  into  two exhaust pipes,  each having a diameter similar to that of the intake pipe so as to establish a 2:1 exhaust/intake flow ratio.   Cross-drilled reburner tubes are installed across the intake ends of the exhaust pipes to provide additional air for complete combustion.  The bottom plates of the storage hopper are free from attachment along their lower  edges,  so  that  these  expand  and  contract  on  a continuous basis with changes in the temperature of the stove; this causes cyclical distortion of the plates which shifts the fuel downwardly towards the discharge opening.

Title: Method of manufacturing thick steel product of high strength and high toughness having excellent weldability and minimal variation of structure and physical properties
Inventor: HAYASHI TOHRU
IPC: C22C38/04
Filed: 1998-06-19
Granted: 2006-08-15
Abstract: A method of manufacturing a thick steel product of high strength and high toughness having excellent weldability with minimal variation of material properties, comprises heating a steel raw material to the temperature of Ac3 to 1350°C, hot rolling and then cooling at the cooling rate of 10 °C/sec. or less. The steel raw material has the following composition:      C: 0.001 - 0.025 wt%;      Mn: 1.0 - 3.0 wt%;      Ti: 0.005 - -0.20 wt%;      Nb: 0.005 - 0.20 wt%;      B : 0.0003 - 0.0050 wt%; and Al: 0.01 - 0.100 wt% balance substantially Fe and incidental impurities.      The composition has a transformation start temperature (Bs) of 670°C or less. Since the steel product obtained by the method has no variation in physical properties regardless of variation in cooling rate, it is possible to supply steel products of high strength and high toughness which have uniform microstructure and properties along their thickness direction and are excellent in weldability.

Granted: 2002-06-04
Abstract: A conveyance apparatus for conveying at least one logging tool through an earth formation traversed by a horizontal or highly deviated borehole is disclosed.  The conveyance apparatus comprises a pair of arcuate-shaped cams pivotally mounted to a support member, means for biasing the arcuate surface of each cam into contact with the borehole wall, and actuators operatively connected to each cam.  A logging tool is attached to the conveyance apparatus.  When either actuator is activated in a first direction, the cam connected to the activated actuator is linearly displaced forward and the arcuate surface of the cam slides along the borehole wall.  When either actuator is activated in a second direction, the activated actuator pulls the connected cam backwards and the biasing means thereby urges the arcuate surface of the cam to lock against the borehole wall. Once the cam is locked, further movement of the actuator propels both the conveyance apparatus and the logging tool forward along the highly deviated or horizontal borehole.

Title: Woven mesh interconnect
Inventor: BUCHOFF LEONARD S
IPC: H01R11/01
Filed: 1998-09-04
Granted: 2002-10-01
Abstract: An electrical interconnect is comprised of a woven mesh in which an array of parallel wires is retained in spaced relation by a transverse array of nonconducting strands, the mesh being enclosed or encased within a resilient matrix. The conductive wires are on a close pitch to yield greater current carrying capacity and achieve a lower more stable resistance.  With this construction a great number of wires are in contact with each contact pad to yield greater current carrying capacity and corresponding lower resistance.  The closer pitch wires also provide greater redundancy of contact points.  This structure can be custom configured in as many layers or in a variety of shapes as is desirable to achieve a given electrical performance.   The woven mesh can be wrapped around a shaped substrate to provide electrical connections in a desired shape.  The woven mesh interconnect can be  integrated as part of a boot,  wherein the boot receives an electrical device therein and the woven mesh interconnect provides electrical connection from the device within the  boot  to outside  the  boot.   The woven mesh interconnect  can  be  layered  and  shaped  to  form  an interconnect   which   not   only   provides   electrical interconnection but also provides a biasing force due to the shape of the device.

Title: Method and apparatus for modifications of visual acuity by thermal means

Granted: 2006-11-21
Abstract: This invention is a thermo-keratoplasty system and method for locally heating and reshaping a cornea in a manner that produces a minimal regression of the corneal correction. The system includes a probe (12) that is coupled to a power source which can provide current at a predetermined power, frequency and time duration. The probe (12) has a sharp tip (36) that is inserted into the stroma of the cornea (48). The tip has an insulated stop that controls the depth of tip penetration. Current flows into the cornea through the probe tip to locally heat and denature the corneal tissue. The denatured tissue causes a subsequent shrinkage of the cornea. A pattern of denatured areas can be created around the cornea to correct the vision of the eye.
